I WALL STRUCTURE.

Application-filed January 25,1928, SeriaiNe. 249,393.

This ,invention relates to an improved wall structure and method of forming and applying the same.

.Heretofore, it Ihas been ,the practice to 5 apply to wallstudding, lfirst the. ship-lap or siding, second, some water proofing material such as tar paper, third, the metal lathing, .and finally the stucco or plaster is applied. These are all separate operations,

each operation adds materially to the cost of the structure. It is the primary purpose of .my invention to .eliminate the necessity of applying the siding and water proofing paper, 'at the time of erection of the structure, by providing a stucco receivingr base consisting of metal lathing-with wall board permanently attached thereto, so that when the structure is to be erected, it

is merely necessary for the operator to secure -the already assembled wall board and lathing to the studding, and the-,only other operation necessary is the stuccoing orv plastering, which may be done in a uni/form and efficient relation, without any consid- .'erable skill. v

Among the very important objects of this invention is the provision of a wall structure and a method of forming and applying the same which willdo away with the conventional operations, of applying siding and tar paper;

even plastered wall surface may be absolutely attained; by which a wall of uniform 'strength and thickness isA secured, and by means of which asolid reinforced sheet Wall lof'cementit-ious material is provided, without voids. v y l Other objects and ladvantages of this invention will be apparent during 'the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts 'l throughout the several views,

Figure 1 is a fragmentary perspective view of the assembled expanded metal and wallboard, showing novel features.

Figure 2 is a fragmentary vertical Sectional view taken through a `wall structure, showingythe application of the improved lathing and wall'board to-studding, and with the stucco or plaster received thereon.

f Figure 3 is a fragmentary vertical secwhich is economical and saving in labor; by means of which an.

tional nview taken through the novel assemblage of wall board and metal lathing.

In the drawingswherein vfor the purpose of illustration is shown only aipreferred embodiment of theinvention, the letter .A may generally designate my ,improved stucco receiving structure', which may `consist of expanded metal lathing B having wall board C secured thereto in a novel relation.

The lathing or sheathing B. is preferably of the expanded metal type, including the body mesh 10, expanded -iIr` the usual manner to provide openings. 11 therebetween through which plaster and stucco may 1'eadily-pass. Preferably parallel ribs 12 are provi-ded upon the lathing B, to'stiffen and reinforce the same; these ribs preferably being of V-shaped formation, and extending beyond the plane of the mesh 10 for any desired distance, according to the typeof `structure in which the wall is being formed.

In the example shown, theribs 12 are of V- shaped formation, with leg or flange portions 13 and 14, exending f rom'the plane of the mesh 1U to the apex or outer 'edge 15, and which edge 15 is normally adapted to abut against the stuccoing or siding inconventional wall formation, as will be .well-un- 4opening 20 will be provided in the rib 12,

and the base of the triangular projection 18 is of course at the ridge line of the rib 12, and extends with its apex or point 23 in a direction normalk to the plane of the expanded metal lathing. These projections 18 are preferaly one-half inch or so in height, andare provided for the purpose of holding and securing the wall board C thereto in a relation illustrated in Figure 1. yThe wall board C may be of composition paper, plaster, gypsum, or the like, although it is preferably water-proof. The'wall board C is4 either rigid or semi-rigid, with an inherent tendency to maintain its form, and it is of a thickness which will permit the same to befoced upon the metal lathing at the rib side of saidlathing, so that the projections 18 of the lathing `are driven through the material of the Wall board to project from fthe outer side 'of the wall board,

l rlhese projecting from the outer side of the wall board 'are then turned over, as shown .the factory, and shipped to contractors and the like for erection in this assembled relation into thebuilding structure. It is of course foreseeable that the expanded `metal with the triangular projections 18 may be assembled with the .wall board C at.the

building site, but for economical and labor savmg yreasons the wall board and lathlng ture A in providing a wall or the like, the

are already assembled when the contractor or architect receives the same.

Referring to the assemblage of the struclathin-g with its water proofed backing or wall board assembled thereto are attached directly to the studding in the same manner -as lathing heretofore has been fastened t studding or siding,` that is, by driving nails or vstaples 51 through or in an embracing relationwith the ribs 12; the wall board` G being faced against the studding 52,- as shown in Figure 2. AS thus secured in place the backing or wall board C Ais against the studding' 52, with' the mesh body 10 of ythe metal sheathing or lathing B Vin uniformly spaced relation with the wall board C. It

is'thus obvious that A'the conventional operat1o1'1s of applymg siding and tar paper or.

vother Water proof paper are done away with during ythe building operation. The plaster or'stucco is then applied, land the operator may easily forcethe stucco into and through `the mesh 10 between the same and the wall board C, vto fill the pocketsand channels therein without the formation: of voids. The

uniform strength; However, with my wall n l board attached to the ribs .of the lathing, in advance of the application of the structure to the studding, the spacing is such` thatthe mortar will pressl evenly intol the v pockets between the lathing mesh andwall board and completely fill the spaces.` This produces a sheet of reinforced cementitious material which gives a uniform and there.

fore increasedstrength to the entire wall structure. The uniformity in` the thick nesses of the 'ppckets in this structure., enables-the contractor to determine accurately the amount of'marterials which any job will require, and thus costs may be determined without speculation.

It is obvious from the foregoing that -a novel structureand method of forming and applying the sam'ehas been produced, which is superior to conventional methods of application and formation."

Various changes in the steps of the method, nnd inthe shape,'size, and arrange- .ment of parts may invention shown and described, without departing from the. spirit of the invention or the scope ofcthe claims.

I claim: 1. Building material consisting of reinforced metal lathing including a mesh body and metal ribs with pointed projections rigid therewith, and substantially impervious wall board secured by the pointed projections on vthe ridge edges of the ribs inspaced relation with the mesh body.

2. A wall structure of the class described expanded metal lathingprovided with integral rigid pointed projections, and wall be made to the form of- 'board secured to said projections 'i spaced relation with the body of said metal lathing. 3. Ready to apply combi-nation wall board and metal lathing comprising expanded metal lathing having a mesh body and ribs Loutstanding therefrom, and wall board se-- cured to said ribs in spaced relation with 'the mesh body. v Y v l 4. Ready to apply combination wall board and met-al lathing comprising expanded j 'metal lathing having amesh body and ribs outstanding therefrom, and wall- ,board seplaster or stucco is then applied to the uni-/cured to'said ribs in spaced relation with l form depth desired over theoutside of the -.nesses, which givesg an' eccentric -and nonthe mesh body, said wall boardbeingsecured l to the ribs by pointed projections'rigid with the ribs and extendingthrough the wall u board and overturned on thewall board at the opposite side from said ribs.
